Let's say on each item of the menu, we want to add subitems. Let's say for "Red colors"
we want to have the items Red, Purple and Maroon. All we need to do is add a new
Easy Menu and attach it to the "Red colors" item. Here's how:

<oem:EasyMenuid="EasyMenu21"runat="server"AttachTo="menuItem1"><Components><oem:MenuItemInnerHtml="Change to Red"ID="menuItem211"></oem:MenuItem><oem:MenuItemInnerHtml="Change to Purple"ID="menuItem212"></oem:MenuItem>...
and so on for every Easy Menu.
